pinctrl: zynq: add CONFIG_OF dependency

The zynq driver can be enabled for compile-testing on builds without
CONFIG_OF, leading to a link error:

ld.lld-21: error: undefined symbol: pinconf_generic_dt_node_to_map
 referenced by pinconf-generic.h:231 (/home/arnd/arm-soc/include/linux/pinctrl/pinconf-generic.h:231)
          drivers/pinctrl/pinctrl-zynq.o:(pinconf_generic_dt_node_to_map_all) in archive vmlinux.a

Prevent this with the proper compile time dependency.
